MEANS FOR MAKING BEDSPRIITGS.

This invention relates to bed springs and more particularly to a system including a method and apparatus for manufacturing an improved mattress supporting fabric and .5 spring device.

An object is to provide a method of and for fabricating a wire fabric which will result in a very strong and inelastic fabric. An object is to provide a method and means for the facile manufacture ofthe improved fabric with a minimum of labor, time and material.

An object is to provide a method for interhooking meeting bights in a clinch having an overlooking bend to obtain a non-unwrapping interlock of the ends of the bights.

An object is to provide for the ready production of a series of fabric units and to provide for the easy interconnection of the requisite units and their respective permanent interhooking. v

The method and apparatus of the present invention are designed to produce, first a double hooked end selvage unit; second, an intermediate or second unit to connect with the selvage unit; and third, a central fabric unit whichdiffers but slightly from the second unit. The method and means of the present invention further provide for the interhooking of the several units, each transversely extending from side to side of the spring fabric; bights of each unit being combined with coordinate bights of the next unit. p

Other objects and advantages of the present invention will be made manifest in the following specification of an embodiment of the invention, it being understood that modifications and variations may be resorted to within the scope and spirit of the invention as it is here claimed.

Figure 1 is a plan of the first or end selvage unit, and Figures 2 and 3 are and views thereof. Figure a is a plan .of the second or intermediate unit, and Figure 5 is an end View thereof. Figure 6 is a per-' spective of a portion of the third type or central unit. Figure 7 is aplan of a portion of one end of the fabric showing attached springs. Figure 8 is an edge view of the first, second and third types of units connected up in the fabric.

Figure 9 is a plan showing one step in the system of making a unit; apparatus therefor being in open position and shown in plan preparatory to over folding selvage hooks. Figure 10 is a left hand front elevation, showing the suspended bend-fulcrum strip. Figure 11 is a right hand elevation showing the folding bar over turned to fold the bars. Figure 13 is a plan (about A size) showing bight bending operations; bow and bight tools being in horizontal section.

Figure 14 is a vertical cross-section, showing the anvil posts projected. Figure 15 is a plan of a portion of the fulcrum strip and Figure 16 is an edge view showing the strip locked by a locking bolt. Figure 17 shows the strip locked and the folding bar turned over to bend the bow. Figures 18 and 19 show means for making the second or bar-end fold.

The fabric comprises an end selvagemember or unit A, an intermediate unit B connected to the 'selvage A, and a body unit C, all made of the same size wire.

As shown in Fig. 1 the unit-A has parallel limbs a which are alternately connected by bows a and cross-bars M. The endmost limbs or are provided with back hooks a perpendicular to the plane of the series of limbs a. The bows a are all folded over so as to form open hook bights to hook onto introduced cross-bars?) of unit B. The crossbars a are also folded at a to form crosshooks to receive a truing rod D, F ig; 7 around which each bar a is tightly wrapped. The ends of the rod D are clinched around the wrap at D Before the .bars a are wrapped on rod D the eyes of springs S are hooked into the folds (L This for'msend selvages (along each end). It will be seen that unit A has staggered bights a a and each of these is-overfolded, and on the same side ofthe unit A. y

, Unit B'has straight cross-bar'sb' not overfolded, to hook into the bows d Alternating with the bars 6 are. bows 6 connected thereto by limbs 5; the endmostof which have closed eyes 6 lying in the plane of the unit. The bows b are overfolded at b to form hook bights. The units C are generally similar to units B but differ in having end bars 0 with limbs c having back turned hooks 0 The limbs c are alternately connected by" overfolded bows 0 Any number of the central or body C units are connected.

A device adapted to be used for removing a Wheel from an axle upon Which it is keyed comprising a body provided at its opposite ends With alined sockets of different sizes, and anvil plugs fitting in the sockets.

In testimony whereof I affix my signature.

CASH A. CLEMONS.

An object is to provide disappearing anvil posts to release the bights of the wire before the folding bar is thrownover to bend the loops over to hook form.

it will seen thateach unit is of a continuous piece of wire from one side to the other of the fabric and that the only wire ends are at the extreme sides of the fabric and these wire ends are disposed under the fabric. The advantage of this is that the applied mattress is protected from raw ends hooking into the mattress. There are no open links to cut the mattress. The fabrication of the method enables each unit to fold in Zig-zagged relation as to the next.
